散熱不足也是影響升降機(jī)使用的因素,為了保障良好的使用效果,需要了解造成升降機(jī)散熱不足的原因有哪些?下面濟(jì)南天銳升降機(jī)械的專家就給大家詳細(xì)分析一下。
Lift manufacturers introduce less heat also a factor elevator use, in order to guarantee good results, you need to understand the causes of insufficient cooling lifts have? Jinan days following sharp lifting machinery experts give you a detailed analysis.
升降機(jī)的工作環(huán)境一般比較苛刻惡劣,如果回油路及冷卻器由于臟物雜質(zhì)堵塞,散熱器和油箱等表面太臟被灰塵、油泥或其他污物覆蓋而得不到清除,則會(huì)形成保溫膜,使傳熱系數(shù)降低或散熱面積減小而影響整個(gè)升降機(jī)的散熱,連續(xù)超負(fù)荷在溫度過(guò)高的環(huán)境工作時(shí)間太長(zhǎng),會(huì)使溫度急速升高;或者升降機(jī)的工作環(huán)境與原來(lái)設(shè)計(jì)的使用環(huán)境溫度相差太大也會(huì)引起散熱障礙。在這種狀態(tài)下如果操作升降機(jī)時(shí)動(dòng)作過(guò)快過(guò)猛等使用不當(dāng)?shù)膭?dòng)作就會(huì)產(chǎn)生液壓沖擊,致使溫度升高,從而使液壓油粘度下降,粘度下降又會(huì)導(dǎo)致內(nèi)泄漏增加,造成油溫的進(jìn)一步升高。
Speaking elevator lift manufacturers generally harsh working conditions poor, and if back to the oil cooler due to the dirt clogging impurities, radiator and fuel tank and other surfaces dirty with dust, covered with sludge or other contaminants and are not cleared, the formation of the insulation film, the heat transfer coefficient is reduced or the cooling area is decreased and affect the entire heat lifts, continuous overload at high temperature environment long working hours, the temperature will rise rapidly; or lift the working environment and the original design ambient temperature difference is too large can cause thermal barriers. In this state, if operated lift too much too fast action such as the use of improper action will produce hydraulic shock, resulting in temperature, so that the hydraulic oil viscosity decreased, viscosity decreases will lead to an increase in the leak, causing oil temperature further increased.
